A report by Colossal spotlights Timothy Boomer’s close-up photographs of insect galls, small plant growths that can shelter and feed developing wasp larvae. Boomer says he uses focus stacking to photograph their fine structures and edits minimally; the report does not identify a new scientific finding or a publication date for a separate project.
Colossal has published a report on nature photographer Timothy Boomer’s close-up images of insect galls, small growths induced on plants by insects including cynipid wasps. The photographs bring attention to the structures’ varied shapes and colors, while Boomer describes using focus stacking to make their fine details visible.
Galls form when an insect prompts a plant to grow a structure that can provide food and shelter for its developing larva. The Colossal report says chemicals introduced by larvae cause the plant growth. Galls can be tiny, appear in clusters, and vary in color, with examples ranging from brown to pink and yellow. Different wasp species produce distinct forms, often on particular parts of a host plant.
Boomer told Colossal that he concentrates on galls induced by cynipid wasps, which he considers especially striking. The report features examples photographed in California, including an urchin gall on blue oak, red cone galls on a valley oak leaf, and a beaked twig gall. It also notes that scientists estimate there are at least about 1,300 cynipid species worldwide.
To record objects at this scale, Boomer uses focus stacking: he takes hundreds, and sometimes thousands, of photographs at different focus distances and layers them digitally. He told Colossal that he makes minimal Photoshop edits, saying he wants to show what occurs naturally rather than enhance the forms. The report points readers to his Instagram account, where he also shares photographs of subjects such as slime molds and flowers.
Making Tiny Galls Visible
The photographs offer a visual entry point into a plant-insect relationship that can be difficult to notice without close observation. A gall is not simply an unusual bump on a leaf or twig: it can be a protective, food-providing environment for a larva. Showing differences among galls helps readers see how varied these structures are, while the captions connect individual forms to particular wasps, plants, and locations.
The report also makes the photographic process part of the story. Focus stacking is what allows viewers to inspect details across a subject that is too small for ordinary close-up photography to render sharply from front to back. Boomer’s stated preference for minimal editing frames the images as documentation of natural forms, not as a claim that the photographs reveal new biological findings.

How Galls Form and Vary
According to the Colossal report, gall-inducing insects prompt host plants to produce growths that support their offspring. In the case of cynipid wasps, a developing larva remains inside the gall as it grows; if development proceeds successfully, it later emerges as an adult. The structure’s shape can differ by wasp species and the part of the plant where it forms.
Not every gall develops in the same way. Boomer described a photographed spined turban gall that differed from the typical appearance he expected: it had a darker pink color, blackened tips, and spikes across its surface. He attributed the variation to another organism entering the gall early in its development. That explanation is his interpretation, not a finding independently established in the report.
“Galls can be brought about by many different organisms, but I tend to focus on the ones induced by cynipid wasps because they are the most visually stunning (at least in my opinion).”
— Timothy Boomer, speaking to Colossal
Limits of the Reported Findings
The Colossal story is a photography report, not a scientific study. It does not describe new research, identify a formal project launch, or provide data testing how particular galls form. The estimate of at least about 1,300 cynipid species is presented as a general scientific estimate, without a cited study or date in the supplied report.
The reason for the atypical spined turban gall is also not independently established in the article. Boomer explicitly said he was not a scientist and described his explanation as his understanding of what happened. The report does not identify the organism that entered the gall or provide further details about its effect.
Where to See More Images
The report directs readers to Boomer’s Instagram for more of his nature photography, including images of slime molds and flowers. It does not announce an exhibition, book, scientific collaboration, or scheduled follow-up, so no further project milestone is confirmed in the source material.
Readers interested in the biology behind the pictured galls would need additional information from researchers or specialist sources. The Colossal report’s immediate focus remains the photographs, their California locations, and the methods Boomer uses to capture small subjects clearly.
Key Questions
What are insect galls?
Insect galls are growths on plants induced by insects. In the examples described by Colossal, they can provide developing larvae with food and shelter.
What does Timothy Boomer photograph?
Boomer photographs natural subjects including cynipid wasp galls. The report features several forms found on California oaks and other plant parts.
How does focus stacking help photograph galls?
Focus stacking combines images taken at different focus distances. Boomer told Colossal he may take hundreds or thousands of frames so the small subject is clear across more of its depth.
Did the report announce a scientific discovery?
No. The source is a report about Boomer’s photography and the gall forms he documents. It does not report a new scientific study or independently verify his explanation for an unusually shaped gall.
